Because is she is beautiful but fearless and thoughtful of Baifern's role. Better is Better than an ordinary role before.

both fl are ceos/hold high profile job post and are hated by everyone in the firm. and consider the fls to be nightmares. ML in both cases are the fls' subordinates. PA in yuttakarn and intern in IIMH
spoiler: the catch is that in yuttakarn, the ml joins fl's firm with an ulterior motive to spy her whereas in IIHM ml has powers and realises fl isn;t actually bad

it's similar except the ml chases the fl instead
the cold boss trying to act cold but are actually really nice to other
